Background

At present, places such as offices, households or school dormitories are basically wooden doors or metal doors with unilateral hinges, when the doors are opened or closed, door leaves are in a suspended state, in the past, the doors incline towards the side with a door leaf lock head or without a hinge due to the gravity of the door leaves, so that the doors are not easy to close, the door frame on the side with the hinge is damaged to a certain extent, and the damage of the doors is accelerated, so that the service life of the doors is shortened. In winter, students in high school or college dormitories often do not have keys when going to a washroom, so that the students in the dormitories feel uncomfortable due to the fact that cold air is blown into the dormitories without closing or locking the doors (other students in the dormitories at the moment). For this reason, there are many students who use adhesive tapes and paper to adhere the door leaves between the door slits together, and increase the contact and friction force between the door leaves and the door frame, so that the door is fixed in a closed state without being blown open by wind in a closed and unlocked state. In the past, the door gap between the door leaf and the door frame with the lock catch is larger, and after the door gap is larger, the door can be easily opened by inserting a card sheet from the door gap, thereby forming a safety problem.

Therefore, how to solve the above problems becomes a focus of research by those skilled in the art.
